These, together with various=ancillary objects: and features areattained by this device, the preferred embodiment of which has beenillustrated, by way of exampleionly, in the accompanying drawingswherein:;

outer-bearing ring 46 whichis press-fitted into; 1

the caps 42, andan inner bearing -race48-which--- is press-fitted on theends of the-shafts'40.--As is apparent from a consideration of Figure 3,antiefriction .3 bearing e1ements2-. 5fla' are 1 disposed incomplementary recesses;laingtheuinnen=and-a;

3 outer bearing races 48 and 46, respectively, whereby the bearingassembly not only serves as a radial bearing but also serves as a thrustbearing to limit axial movement of the shaft 40 relative to the housing.

The shaft 40 includes a central portion 54, an intermediate portion 56of relatively reduced diameter, and an outer end portion 58 of adiameter less than that of the intermediate portion, the inner bearingrace 48 being pressfitted on the outer end portion and abutting theshoulder 60, between the intermediate and outer portions of the shafts40.

A pair of drum-forming disks 62 and 64, having an outwardly flaredperipheral rim 66, each has a central opening 68 which is reinforced byan annular washer I8, which is spot-welded to the disk, the disks andwashers being pressfitted onto the central portion 54 of the shafts 40,and non-rotatably keyed thereto as by the key I2.

A split, spirally formed band I4 is disposed between the disks 62 and64, which band is provided with a plurality of outwardly extending earsI6 which extend through the spirally positioned apertures I6 in thedisks 62 and 64, which ears are bent so as to abut the outer faces ofthe disks 62 and 64, and thereby detachably retain the disks and thesplit ring members I4 in engagement with each other. As will beappreciated from a consideration of Figure 6, the ends of the splitbands "I4 are offset from each other to permit the passage of theflexible hoses 80 therethrough, without necessitating a sharp bend inthe hose.

In order to yieldingly bias the shafts 40 and the reel in a direction towind the hose 80 thereon, there is provided a helical spring 82 whichhas the inner end thereof secured, as by a pin 84, to an annular hubmember 86, which hub is non-rotatably attached to the intermediateportion 56 of the shafts 46, as by a key 88, the pin being disposed in asuitable recess 90 in the hub member. As is apparent from aconsideration of Figures 2 and 3, the hub member 80 abuts the shoulderbetween the intermediate portion and the central portion of the shaft40. The outer end of the helical spring 82 is secured, as by a pin 92 toone of the side walls, such as I4, of the housing. A spring shield plate94 having a peripheral rim 96 and an outwardly extending flange 98 isdetachably secured to the side walls I4 as by the nut I which is carriedby the pin 92, a plurality of such pins preferably being provided, oneof which serves as the anchor for the outer end of the helical spring82. The shield plate 94 has a central opening I02 which abuts thepacking ring I04 which is disposed above the central portion of theshafts 40, the shield plate also engaging the inner edge of the hubmember 86, in a manner clearly apparent from a consideration of Figures2 and 3.

A pair of centrifugally actuatable pawls I06 are pivotally attached tothe disk 62 by means of stub shafts I68 which are secured to the disks,the pawls being selectively engageable with a notch H0 in the flangedsleeve H2 which is secured to the side walls I2 of the housing. It willbe readily appreciated that whenever the disks 62 and 64 are rotated ata relatively rapid rate, the pawls will be centrifugally actuated into aposition out of engagement with the notch H0, but whenever the disks arerotated at a.relative1y lower rate, the pawls will be gravity-actuatedinto engagement with the notch.

The shaft 40 is provided with a pair of longitudinally extendingpassages I I4, each of which has an offset portion H6 extending radiallyof the shafts 40, an opening between the disks 62 and 64, a pair ofsubstantially L-shaped pipes H8 having one end thereof threadedlyconnected to the shafts 40, in communication with the passage H4, beingdisposed between the disks 62 and 64, and communicative with theflexible hose 80, by means of a coupling I20. The outer ends of theshafts 40 are provided with an internally threaded counterbore I22 whichcounterbore threadedly receives one end I24 of an anti-friction bearingcup I26. An outer bearing race I28 is slidably fitted into the cup I26and abuts a shoulder I30 which limits inward movement of the outerbearing race I28 relative to the cup, the inner bearing race I32 beingslidably fitted on a sleeve I34 which is rotatably disposed within thebearing cup I26. The sleeve I34 has an outwardly flared end I36 whichengages the inner end I38 of the bearing cup I 26, a hose elbow I40being threadedly received on the outer end I42 of the sleeve I34, thehose coupling abutting the inner bearing race I32, in a manner clearlyapparent from a consideration of Figure 3. As is conventional, suitableanti-friction bearing elements I44 are disposed between the inner andouter bearing races, in corresponding recesses I46, whereby the bearingassembly serves not only as a radial bearing but also as a thrustbearing so that tightening of the hose elbow I 40 on the sleeve I34 willurge the outwardly flared inner ends I36 of the sleeve into engagementwith the inner end of the bearing cup I26. The elbow I40 has aconvoluted extension I48 extending therefrom, for the reception of asuitable conduit I50 which is connected to the source of supply (notshown). An annular packing ring I52 is disposed about the sleeve I34between the inner bearing race I32 and the offset externally threadedportion of the cup I 26, to further aid in preventing the escape offluid through the coupling, the packing ring I52 further serving toyieldingly bias the flared end I36 of the sleeve I34 into seatingengagement with the inner end I38 of the bearing cup I26, when the elbowI40 is tightened against the inner bearing race I32.

It is intended that the winding and reeling apparatus set forth isutilized to selectively wind and unwind a pair of hoses which areadapted to convey oxygen and acetylene to the welding and cuttingtorches, which are connected by couplings I54 to the hoses 80. It isaccordingly intended that the spaces between the disks 62 and 64 be suchas to snugly accommodate a pair of the hoses 80, in sidewise alignment,as is best shown in Figure 2.

The housing of the winding and reeling apparatus is connected to asupporting structure by means of brackets I56, which are connected tothe housing, as by fasteners I58, which brackets may be of any suitableconstruction, depending upon the type of supporting structure to whichthe housing is to be attached.

From the foregoing, it is thought that the operation and construction ofthe device will be readily understood, and further discussion istherefore believed to be unnecessary. However, since numerousmodifications will readily occur to those skilled in the art after aconsideration of the foregoing specification and accompanying drawings,it is not intended to limit the invention to that shown and described,but all suitable modifications may be resorted to falling within thescope of the appended claims.
